Quintillions is the name that Kadon Enterprises gives to their beautiful wooden version of Pentominoes . The name 'pentominoes' comes from the resemblance to dominoes, which are composed of two adjacent squares (albeit with dots on them). The twelve pentominoes in Quintillions are all of the possible planar arrangements of five cubes, in this case, laser-cut from maple. An included gameboard allows gameplay with the rules included, and the enclosed pamphlet shows many different shapes which are puzzles to be constructed with the pieces.

Enjoyment of the geometric properties of these shapes is greatly enhanced by learning their names, so as to become separately acquainted with each of the shapes. In the picture below, the shapes, roughly from left to right and top to bottom, are identified with these letter names, which bear an obvious relationship with the shapes: L, Z, Y, T, N, P, W, F, I, U, X, and L.
